Scientometric analysis of research in the field prefabricated construction

Introduction. State policy in the field of housing construction, providing the increase in the volume and decrease in the cost of housing construction, promotes to the development of prefabricated construction. In its turn, the increase in the prefabricated construction requires studying and introducing modern organizational and technological solutions for the erection of buildings and production of precast reinforced concrete structures, determining the directions of improvement of prefabricated construction. Materials and methods. To study the development and effectiveness of prefabricated construction, actual directions and tendencies of scientific research in the field of prefabricated construction, the structure of citation of publications, key researchers, leading countries, institutions, scientific journals a scientometric analysis was carried out based on the SciVal analytical system using visualization tools, quantitative and qualitative scientometric metrics. Results. Analysis of research trends in the field of construction and building technologies in the world has shown that prefabricated construction is one of the most intensively developing and promising areas of research. The main subjects of research in the field of prefabricated construction are design and information modeling, organization of prefabricated construction and production, delivery of structures to the building site and their assembling, at that, less attention is paid to the research in the field of production technologies of precast reinforced concrete structures in the factory conditions and production management, for which further research in these directions is needed. Studies of the development of industrial house-building in the practice of housing construction have shown that the efficiency of prefabricated construction must be considered in the context of a particular country or region and evaluated by applying a systematic analysis of costs and benefits. Conclusions. The results of the executed scientometric analysis make it possible to identify trends, priority areas for further scientific research and their relationship with other areas of science, and can be a scientific basis for identifying gaps in current research in the field of prefabricated construction.
